Tov all whom it may concern;

Be it known that I, PIERRE GIRIN, a citizen of the Republicof France, residing in Paris, France, have invented .certain new and usef ul Improvements Vin Rolling-Mills, of which the following is a specification. e

Bars of small thickness and considerable length, such as hoopiron,`.when they leave' the rolling-mill in which they have been manufgtnre.d-are-extremely flexible owing to their high temperature.,l In order lthatv it is necessary to exert a certain amount of 'from the rolling-mill.. This'traction may be exerted by operatives who seize the extremity of the bar by means of tongs and go away from the mill, running if it is a high-speed mill. Thisv work'is exceedingly onerous, and4 accidents are liableto happen. Y

This invention'consists offan apparatus by which is mechanically effected the drawings This apn paratus is based upon the following princiarranged two conveyers constituted by endless bands upon which the rolled bars are successivelyguided upon leaving vthe mill of which is adapted to'fbe displaced, Pref Figure 1 of the accompanying drawings is an elevationof the apparatus upon the operd` ating side. Fig. 2 is a front elevation. Fig. 3 is a plan view.; and Figs. 4-and 5 represent the apparatus as a whole, its median portion being broken for convenience `of representa- According to this invention the two convey.-

manner as band-saws. They upper length slides in Ll-shaped guides resting jupon the ilooring of the workshop, while 'the -lower sean 10.104.311. ons man.)

length travels in an appropriate trench. The

tension` of these two' lengths. is obtained by means of counterweights F', which'act upon the pulleys F. `The rolled bars upon leavingthe finishing-cylinders A of the rolling-milll are directed upon the`-end1essbandsbya channel B, whichis adapted to loe-displaced by means of a lever H and a connecting-rod J in such a manner that its extremity is brought either above or in the middle of one or other oit'V the endless bands. At the same time` said lever I-Ioperates, by means of connecting-rods I, friction-clutches E, by means o f which movement may be imparted to the pulleys D, which are the driving-pulleys,- for the endless bands. TheI movement is transmitted tothe apparatus by means ofa suitable shaft G.' Upon operating the abovedescribed lever H one of the pulleys D is caused to rotate, and at the same time the ex. tremity of the channel B is brought above the band in movement.

While one bar is being roueathe est pre vlously rolled, which is uponthe conveyor which is at rest, is removed. l

4The apparatus is driven from the rolling# .mill itself, and the velocity of the endless bands is slightly greater than thatof the bars leaving the mill, so that any bending'ef these `ilexible bars is prevented.

The combination with finishing-cylinders -of a rollingmill,'of'a plurality of conveyors, means for directing a bar from said cylinders to either of said conveyors at will, driving mechanism, andV means forsimultaneously actuating said directing :means and clutching j to the driving ymechanism Vthe conveyor to which said bar is directed. e
